This idea, depends on availability; but my initial gut reaction, was "Why not use old buses ?" Windows already installed; remove the roof-'skin', add a few hoops to help hold up a sheet of clear plastic. And; install a row of beds, on each side. Portable (You; might need a tractor.); depending on the configuration & size of your property (And; your opinions, about the aesthetics.) you might wish to move it for the 'Off' season. So; you can put it out of sight.
Some extras could be :
- If the bus; is not drivable; disconnect the wheels from the transmission & brakes, if that would help it to roll easier (For those; that want the portability). And; use big chunks of unsplit firewood, as parking blocks. Removing the engine, & gutting the transmission; would help to make it lighter. But; depending on how much wind you get, don't make it so light that it blows onto its side.
- Take the sides off, down to the floor; and replace with clear plastic. If; the sides are 'uni-body' without any real frame, it might be better to cut holes in the sides (Or; remove the metal like I mentioned earlier, & use studding to hold the windows up & provide 'nailing' for the plastic.) & then replace with clear plastic. This option; should be only considered, in light of what is expected for 'snow load' & 'wind load' in your area.
- If; you ignore the previous option & want to make it look nicer, then paint it. Your colour(s), flowers, other plants, etc.
